Analysis of the Resonant Wavelength Router

Introduction In the last years ring resonators attracted the attention of many researchers, mainly thanks to the selective frequency response, the small dimensions and because they can be exploited as the main building block of an add-drop, a de-multiplexer or even a crossbar matrix. In this contribution the integrated optic crossbar matrix based on ring resonators, named Resonant Router (ReR) and shown in Fig. 1, is described and its application as wavelength router (λ-ReR) is investigated. The nodes characteristics are described and the routing performance in terms of Q, extinction ratio and BER are discussed. An effective method for the estimation of the impact on BER is also presented. Preliminary experimental results on a single node realized with one ring conclude the contribution.
